Using a contentious book to sharpen the opposing case

A clear statement of the opposing position exposes assumptions and prevents an argument from ignoring its strongest challenge. Anthony Cumming's account questions familiar RAF success ratios by examining the concentration of victories among a small group of pilots. It also raises shared claims, incomplete sourcing, and the choice of which commands to include in the loss totals. British aircraft brought down over home territory could sometimes be recovered and repaired, an advantage that raw loss claims may obscure but which was not universal. The book is therefore useful as a forceful provocation to test against other evidence rather than as settled proof of its revisionist case.
